feat(cli): v0.1.6 — name-based peer routing in send_message

resolveClient() now resolves display names via list_peers WS query.
Supports exact match, partial match (unique substring), and falls
back to pubkey/channel/broadcast pass-through.

  * Given a `to` string, pick which mesh to send from. Strategies:
- *   - If `to` looks like a pubkey hex (64 chars), try every client;
- *     caller is expected to know which mesh the pubkey lives in.
- *   - If `to` starts with `#`, treat as channel on the first mesh.
- *   - Otherwise try to match a displayName (TODO — needs list_peers).
+ *   - If `to` looks like a pubkey hex (64 chars), use as-is.
+ *   - If `to` starts with `#`, treat as channel.
+ *   - If `to` is `*`, treat as broadcast.
+ *   - Otherwise resolve as a display name via list_peers.
  *
- * For now the MVP: if only one mesh is joined, use that. Otherwise
- * require the caller to prefix with `<mesh-slug>:`.
+ * Explicit mesh prefix `<mesh-slug>:<target>` narrows to one mesh.
